life cycle study of a product is an accepted method for determining the side effects of its production process on environment during its complete life cycle. in this research, the impacts of global warming, acidification, terrestrial eutrophication and fossil resources depletion per unit yield of wheat (ton) on environment were investigated using life cycle assessment method in marvdasht region...
Poultry industry is an important production system due to providing remarkable portion of the human food and protein needs. Considering the necessity of environmental protection, the amount of environmental impacts of a turkey production unit in Iran was determined using life cycle assessment method. The required information were collected through questionnaires and interviews with farm owners....
Background and Objective: The steel industry is the world's largest consumer of energy. A large amount of iron waste is produced annually, which its use in the steel industry can be economic. The purpose of this study was to investigate the environmental impacts of the steelmaking from iron scrap as a raw material using a life cycle assessment (LCA) method. Materials and Methods: Simapro softw...
Poultry meat with a high share in the food consumption is one of the most basic products for supplying protein to households. Due to the high amount of pollutants in this part, the environmental impact of the production of this product is necessary. In the present study, the environmental impact of broiler chicken production in both industrial and traditional breeding methods were evaluated ...
Previous Life Cycle Assessment (LCA) studies of biomass briquetting have shown wide variations in the LCA outcomes as a result methodological parameters and technological parameters. An model was therefore developed to enable transparent comparison life cycle environmental impacts with individual or blends feeds variety options. The according standard procedure ISO14044. A comparative approach ...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
The purpose of this study is to assess the energy savings and emission reductions of the present rural biogas system in China. The life cycle assessment (LCA) method is used to analyze a "pig-biogas-fish" system in Jingzhou, Hubei Province, China. The nonrenewable energy cost and the greenhouse gas (GHG) emissions of the system, including the pigsty, the biogas digester, and the fishpond, are t...
Abstract The objective of this study was to analyse the life cycle coconut oil industry and process improvement alternatives. analysis (LCA) method are based on scope gate gate. This shows that input for production consists copra as main raw material several supporting materials energy. outputs oil, pulp pellets, waste (liquid, solid, gas). total potential GHG emissions, acidification, eutrophi...
